Eramet's Moanda (Gabon) manganese mine feeds electrolytic manganese dioxide (EMD) for batteries. Our lithium extraction from Centenario Ratones brine (Argentina) uses direct lithium extraction (DLE) — no evaporation ponds.

Guoci's barium titanate nanopowders fill the multi-layer ceramic capacitors (MLCC) in every smartphone — 1000+ layers per chip, each 1 micron thin. Electronic ceramics at nanoscale precision.

Yunnan Energy's wet-process separator films — microporous PE membranes 5 microns thin — prevent internal short circuits in EV batteries while conducting lithium ions. The membrane that keeps cells safe.
